Title: Radar monitoring systems
IPC: G01S13/87
Filed: 1971-06-18
Abstract: 1396284 Secondary radar systems ASSOCIATED ELECTRICAL INDUSTRIES Ltd 19 June 1972 [18 June 1971] 28760/71 Heading H4D In a radar monitoring system for determining the range of craft, each has a radar responder which is energized by a radio transmission unique to that responder, the radio transmissions being completely separate from the radar transmissions. In a surveillance area, e.g. canal leading to dock area, interrogation stations are situated at 4-5 mile intervals. Each ship entering the canal is issued with a radar beacon including a UHF radio receiver and X-band radar receiver-transmitter. Each beacon has a unique two-tone audio coding which is decoded by the UHF receiver to energize the radar receiver-transmitter. This comprises an X-band receiving-transmitting aerial and a delay line canceller to detect the primary radar pulse pairs. 64 Ásec. after reception of a pulse pair, a single reply pulse is transmitted at a slightly different frequency to the interrogation pulses. The system includes a central control station which transmits one UHF code every 1À5 sees. The interrogating station, Fig. 2, receives this at antenna 17 and retransmits the code at a different frequency via up- and downstream aerials 7, 8. Each code is detected and used to trigger a generator 13 which enables sequentially pre-amplifiers 14 connected to up- and downstream radar antennae 1, 2. Generator 13 also triggers transmitter 5 to radiate several hundred primary radar pulse pairs per code. Each transmitted pair resets counter 26 to zero after a 64 Ásec. delay 25. Reply signals pass threshold 28 and gate 20 and read the range measurement into decoder 27 which sets the measurement into one of twenty range cells 19 each of which comprises a counter. At the end of a complete code cycle counters 19 thus contain a distribution of ranges. After a delay 24 unique to each interrogator, selection logic 16 analyses the distribution to pass the most likely range to generator 25, which adds a digit representing up- or downstream, an interrogator identifying code and a parity check digit. This signal is then relayed via the UHF aerial 17 to the control station. Delay 24 ensures that each interrogator replies in the correct order.

Title: Improved method of and apparatus for coiling or winding wire in helicoidal form
IPC: H01K3/04
Filed: 1929-09-24
Abstract: 319,667. Naamlooze Vennootschap Philips' Gloeilampenfabrieken. Sept. 25, 1928, [Convention date]. Wire.-Wires for springs, i filaments of incandescent electric lamps, &c., are formed into helices, without the use of a core, by conducting them between two co-operating surfaces, internal and external respectively, one at least of which has movement with respect to the wire. The wire is conducted between bodies 10, 11, either or both of which may be rotated, the co-operating surfaces of which may be respectively a convex cone and a concave hyperboloid of revolution. From the neck of the body 11 extends an integral or separate tube 12 which may be tapered so as to feed the expanding helix after formation. In one form the body 10, Fig. 7, may be driven by a belt pulley 23 on ball bearings having a limited universal freedom on a support 30 which is angularly adjustable on an arc 24 and the body 11, which is rotated by a belt pulley 27, is pressed by springs 25, 26 or by hydraulic means into contact with the body 10. The wire is fed at constant speed by feed rolls 28, 29. In a modification, a coiling head 38, Fig. 9, with wire spool 39 is rotated about a fixed shaft 40 and carries an angularly adjustable body 10. Lubricant may be previously supplied to the wire or the bodies 10, 11 may be immersed in a lubricating bath. The wire may be heated during coiling, preferably by making the bodies 10, 11 and the wire supply device the electrodes of an electric circuit. The coiled wire formed as described has one or more polished designs thereon in the form of a band or streak produced by the friction of the coiling surfaces. The pitch of the helix may be varied by varying the speed of the wire relative to the forming bodies and may have portions almost straight due to the pull caused bv the tube 12. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification in which the head 38 is coaxial with and rotates about the body 10 which is adjustable angularly with respect to the body 11 but does not rotate. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in a bearing arrangement between the car body and truck bolster of a railway car
Inventor: HEATER CHARLES LEWIS
IPC: B61F5/16
Filed: 1954-10-08
Abstract: 755,392. Mounting bodies on railway vehicles. AMERICAN STEEL FOUNDRIES. Oct. 8, 1954, No. 29054/54. Class 103 (6). In a bearing arrangement between the car body and truck bolster of a railway car, comprising a centre bearing secured to the truck bolster and slidably engageable with a centre bearing on the car body, the bearings are elongated to provide engageable bearing surfaces at opposite sides of the transverse vertical centre plane of the bolster and abutments are provided on the centre bearings to limit relative rotational movement. As shown in Figs. 1 and 2, a truck bolster 2 is formed on the top wall with a centre bearing 12 bounded by arcuate ribs 16 at the ends and converging into 18, 20 at the sides. An upwardly-tapering king-pin 26 is provided at the centre of the bearing, and the bearing sup - ports a centre bearing 44 of a car body bolster. The bearing 44 has a central opening 48 and spaced depressed portions 52, Fig. 5, which have downwardly-facing bearing surfaces 56 spaced a substantial distance from the opening 48, so that the friction between the two bearings 12, 44 is adequate to prevent or reduce horizontal swaying of the car body arising from irregularities in the rails. Relative rotation between the bearing 44 and the track bolster 2 is guided by convex surfaces 57 on the bearing 44 and concave surfaces 25 on the bearing 12, and the rotation is limited by the engagement of parallel edges 59 on the depressed portions of the bearing 44 with converging ribs 18, 20 on the bolster bearing 12. The bearings 12, 44 may be reversed with the bearing 12 provided on the car body and the bearing 44 provided on the truck bolster. In a modification the kinpin is removable and the bearing of the truck bolster is formed as shown in Fig. 8, the converging ribs 18, 20 being interconnected respectively by arcuate ribs 104, 106 with the centre bearing of the car body correspondingly shaped.

IPC: F24H1/12
Filed: 1928-10-11
Abstract: 323,807. Chapman, F. W. Oct. 11, 1928. Internally-fired boilers.-In water heaters the central space to which combustion gases first pass is surrounded by a water space through which pass tubular ducts extending between apertures in the two walls of the water space. The apertures are distributed over a substantial part of the height of the walls, so that part of the products of combustion can flow outwards through the side walls of the water space near the bottom and part at higher levels. Two examples are shown, one, Fig. 1, in which the water chambers are sealed, and the other, Fig. 4, in which the heating gases can come into contact with the water. In Fig. 1, water passes from a jacket b to a bell-shaped water-space C, from which it is conveyed through the compartments k, l to the delivery e. Ducts n permit the passage of heating gases through the water-space, these ducts being arranged in two or more rings. In a modification (not shown), an additional bellshaped water-space is interposed between the shell c and the jacket, this space also having rings of perforations such as n. In Fig. 4, the water enters at N and passes by way of and through 0 on to the plate L, part flowing through the slit Q to the plate H and into the water-way D, part being conducted by tongues M on the periphery of the plate L to the outer jacket A and part falling into the jacket B. The heating gases expand successively through the tubular ducts E and C into the space between the jackets A and B and to the flue. Hot water collects in the space R. A construction of heater is described in the first Provisional Specification which resembles that shown in Fig. 4, except that the three casings inner, intermediate and outer are single, the inner is perforated, the intermediate is corrugated and is attached to the outer by radial fins. Baffles are fitted over each aperture in the inner casing to prevent entry of water. In the second Provisional Specification, the wall of the intermediate casing and also the outer wall may either of them be formed with vertical pockets, which the water fills and overflows, the intermediate casing being preferably perforated between the pockets. Alternatively, the water pockets may take the form of encircling bands.
